Definitions

  • a resetting circuit 53 is provided for the timing element 12, for the integrator 20, for the threshold value switch 41, and, for any other resettable circuit components.
  • the reset signal is derived from the output of the limit or threshold value switch 41 which is connected to a mono-flop 51.
  • the output of the mono-flop 51 is connected to an impulse lengthening element 29 or is connected directly to one input of an OR-gate 52.
  • the output of OR-gate 52 is connected to an impulse lengthening element 53 which produces at its output the reset signal.
